1.	One litre each of 1M Al_(2)(SO_(4))_(3) and 1M BaCl_(2) are mixed. What is the molarity of sulphate ions in the resultant solution?
Answer» SOLUTION :EQ `Al_(2)(SO_(4))=1xx1xx6=6eq`. eq. `BaCl_(2)=1xx1xx2=2eq`. `THEREFORE eq [SO_(4)^(2-)]` left `=6-2=4` eq `therefore [SO_(4)^(2-)]=(4)/(2)=2N=1M`
